UNITED [STATES My present invention has reference to a liquid cooling device, and has for its primary object the provision of a device in which liquid will be cooled and retained in a cooled condition for an extended length of time.

A further object is the provision of a liquid containing and dispensing device in which dry ice is employed as the refrigerant and which includes means for preserving the dry ice for a v greater length of time than is ordinary, sustaining the ice in a chamber that is divided from the liquid containing compartment, providing means .v for hermetically sealing both of the compartments, and also provided with means for directl6 ing the gases from the refrigerant chamber into and around the liquid containing compartment and likewise means for permitting such gases to escape to the atmosphere. I

The invention will be fully and comprehenlowing detailed description when read in connection with the accompanying drawings which form part of the application, with the understanding, however,- thatthe improvement is capable of extended application and is not confined to the exact showing of the drawings nor to the precise construction described and, therefore, such changes and modifications maybe made therefrom as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.

In the drawings: Figure 1 is an approximately central longitudinal sectional view through the improvement.

Figure 2 is a sectional view approximately on the line 2-2 of Figure 1.

Figure 3 is a perspective view of one of the latches- Figure 4 is a greatly enlarged sectional view approximately on the line 4-4 of Figure 1.

Figure 5 is a sectional view approximately on the line 5-5 of Figure 4.

Figure 6 is a detail elevation to more fully illustrate the means for latching the cover on the 45 device.

The body 1 of the improvement is preferably in the nature of a cylinder having a closed bottom and an open top. The body 1 is preferably of sheet steel'whose seams are welded and both the inner and outer surfaces of the body are baked with white enamel. This is especially true with respect to the inner surface as the body 1 provides the liquid container and the enamel renders the samesanitary. Both of the enamel faces assist in rendering the container impervious and free from atmospheric influence. The container 1 has one of its sides, at its bottom provided with an outlet opening to which is attached a faucet 2.

The faucet is preferably of the pressure type and sively understood from a consideration of the folthe spring influenced valve therein is, of course, normally seated.

In the bottom of the body or container 1 there is arranged a wire and spider-like support 3 whose upper and central portion is of cup-shaped '65 formation and is indicated for distinction by the numeral 4. The open or skeleton rack or support 3 is of aluminum alloy wire, and the upper concave -or cup-like portion thereof receives therein the bottom of the cylindrical body 5 that provides the refrigerant chamber. The chamber 5 also has its top open, and the rack or support 8 spaces the chamber from the container 1, ar-. ranging the said chamber in the center of the container.

The chamber '5 is of aluminum and has arranged therein and spaced from the side and top walls thereof a reticulated basket 6 which is also of aluminum.

Resting on the bottom of the basket 6 and 30 holding the said basket on the bottom of the chamber 5 there is a disc 7. The disc is of a soft hydrous body, such as soapstone or talc.-

The closure for the body'is indicated by the numeral 8 and has an outstanding peripheral grooved bead 9 in which is seated a ring gasket 10. The closure for the cylindrical refrigerant chamber 5 is indicated by the numeral 11 and is also provided with a peripheral outstanding grooved bead 12 in which is received a compres-' sible ring gasket-l3. The disc closure 11 is secured to the disc closure 8 by double headed rivets 14, there being arranged around the rivets and in'contact with the confrontingfaces of the closures 8 and 11 spacer sleeves 15. To two of the rivets 14 on the ends thereof that extend through the closure 9, there is secured an arched handle 16. The closure 8, at spaced intervals, has its beaded edge provided with cam ribs 17 and there is pivotally secured on the sides of the container 5 1 the lower ends of latch plates 18. Each latch plate has its upper end formed with a lateral extension 19 whose outer edge is flanged downwardly, as at 20, and on each extension 18 there is a finger piece 21, whereby the latches may have their ends 19 swung 'over the cam ribs 17 for securing the closures 11 and 8 on the chamber 5 and body orcontainer 1 and to establish a hermetically sealed joint between the said closures,

chamber and body. The downturned flanges 20 no contact with the irmer faces of the cam ribs 17, as disclosed by Figure 1 of the drawings.

- The closure 11, at the center thereof, is provided with a round opening surrounded by a flange 22 whose outer 'end .is in contact with the inner face of the closure '8 and may be welded thereto. The flange 22 is provided with a lateral port 23. The closure 8 is also provided with a central opening surrounded by an outwardly extending and exteriorly threaded flange 24 whose here alines with that oi the flange 22. Arranged f or turning in the cylindrical flanges 22 and 24 there is a short tube 25 that has a port 26 to aline with the port 23. Centrally fixed on the outer end of the tube 25 there is a plate 27 formed with laterally extending shoulders 28 that rest on the outer end of the flange 24. The outer edge ofthe plate 27 is arched, as at 29, and is disposed opposite the inner arched portion 30 of a capmember 31; The arched or. dome-shaped portion 30 of the cap member is provided with restricted apertures 32 disposed directly opposite the arched edge of the plate 27. The cap member has an outwardly extending portion 33 which is periph- 'erally milled and provides a hand grip or wheel and from this portion 32 the cap has an interiorly threaded extension 34 that is interiorly threaded to engage with the threads on the flange 24. The elements just described provide the vent gdQf-or the device. By screwing the cap until the 'same contacts with the periphery of the plate 27 the vent opening 32 will be closed, but there will be a frictional engagement between the dome-shaped top of the cap and the plate 27 suflicient to tur t tube 25 to bring its port 26 into or out of alinement with the port or aperture 23. It is to be understood that a quantity of dry ice is arranged in the chamber 5, and

4 rests on the soap stone disc '7 and is prevented from contact with the chamber by the reticulated basket 6. The gases from the ice will be directed through the registering ports or apertures 26 and 23 and will be caused to circulate around the interior of the container 1 and the liquid therein.

The liquid, of course, is poured into the con- 6 4 The hermetically sealed device will preserve the dry ice for a greater period of time than can the same be preserved by any other means known to me. By turning the cap in a second direction the same will be brought away from the plate 5': 27 so that the gases generated by the dry icev in the chamber 5 can escape through the restricted port or aperture 31 tothe atmosphere.

Gases generatedby the dry ice will first col- Iect between the reticulated basket 6 and the inner face of thecylind rical chamber 5 so that the same will slowly circulate therefrom around the interior of the container 1, which, of course,

adds to the cooling efiect of the liquid in the container. As is well known dry ice evaporates very quickly and by placing 'the soapstone disc '1 in the bottom of the chamber 5 or rather in the bottom of the basket 6, and upon which soapstone the dry ice rests the said disc 'l'will absorb and consequently accumulate the cold that is passed off of the dry ice which also assists in preserving the ice and likewise the said disc in throwing of! its accumulation will assistin' cooling and retaining the liquid in'the container 1 in a cool condition for a greater length of time 5 than could otherwise be accomplished by theemployment of dry ice as a refrigerant. With my improvement the liquid is cooled in a quicker manner and at a' lower degree of temperature,v

description when read in connection with the accompanying drawings will fullyand clearly set forth my improvement, its construction and advantages so that further detailed description will notbe required.-
